Hi all.
I am trying to emulate a togglebutton/checkbox in a custom toolbar.
Right now I have settled for having two toolbar buttons with
different icons. Only one of them is visible and when it's pressed it
toggles the visibility of both buttons using the code below (which
sets visibility of a single button with a given label).
It works OK but only as long as the user doesn't fiddle with button
visibility :-). Is there a way of changing a toolbar button's icon
directly from Basic code ? I could not figure out how to do it.
Hi Jan,
Your solution looks it a little bit strange. You can set the image of
a toolbar button with the help of an image manager. Look at the
following Basic code which uses the image manager to set an image for
a button that references a Basic macro. I am sure you can adapt the
code to your needs.
Hi Carsten.
Thanks for this. I was looking for something resembling Excel VBA where
you just change the .FaceId property of a toolbar button which I can now
see is definitely not the way to do it in OpenOffice.
As far as I can understand icons are instead associated with a command
URL and not the user interface element. So if I change the command URL
of a toolbar button the icon changes with it. This actually makes good
sense for my usage scenario.
I have a toolbar button that is used to turn a feature on or off. When
the button is pressed to turn the feature ON I change its command URL to
point to the Sub that turns the feature OFF. This also changes the icon
so the end user can see the current state of the feature (is it ON or
OFF ?). As illustrated by the code below.
Cheers
